HTML and Meta tags - do they help your website?
HTML and Meta tags - do they help your website? HTML lang tag The following can help to inform search engine robots on the language of your content, using the HTML tag like this:
html lang="en-GB" This can help when indexing your website as per language (and may improve your country specific listing too).
You will find more on this here:
http://tlt.psu.edu/suggestions/international/web/tips/langtag.html
and http://www.w3.org/International/articles/language-tags/Overview.en.php
Meta tags The robots tag - which some recommend using is the robots tag with the content attribute set to NOODP like this:
META NAME="ROBOTS" CONTENT="NOODP" I would suggest you DO NOT use this as it tells the robot NOT to use any of the
Open Directory Project descriptions. Think about this logically, the ODP is a human edited directory and is still one of the most trusted sites for website descriptions in the World, and you are telling the robot to not use it. If you were that robot collecting that data you wouldn't then trust that website, and maybe decide to exclude it or flag it for manual checking, either way the outcome is not good. Read more on
the GoD (Google official documentation):
Google on meta & robots Do use the the tags:
META "description" CONTENT="Where/why you should host your website..."
META NAME="keywords" CONTENT="UK web hosting, location country, google listings, etc" But do not over use these and do not expect them to provide you with a massive boost.
So correct HTML can help, as can meta tags but they can also hinder your website, so add them with care. And remember to ensure your website is listed within Google's country-specific saerch results you must
host in your native country (or at least be using a country specific domain name, e.g. website.co.uk).
Happy webmastering everyone
Dave.

Googlebot: Preventing Duplicate Content
Duplicate content caused by your root AND index pages being indexed
You can find your content being indexed for the root and the index.php (the default page which can also be: index.html, index.htm, default.html, index.asp, etc.) pages like this:
www.Mydomain,com/index.php AND www.Mydomain,comEspecially if you have inadvertently linked to the index file (www.Mydomain,com/index.php), rather than the root (www.Mydomain,com). This situation can and often does occur with subfolders too.
Duplicate content caused by multiple domains on the same web space
Do you have more than one domain mapped to the same website/web content?
If so then you are not alone. This can have a negative affect on your pr and SEO.
Consider the affects it can have on search bots (googlebot, etc) finding duplicate content:
finds domain1 then domain2 which both map to the same web space. It could then decide to drop domain1 in favour of domain2, or worse still drop both domains!
Duplicate content caused by your domain being indexed with and without the "www" www.Mydomain,com AND Mydomain,comThis is just like having two domain names pointing to the same content, it creates duplicate content.
So what do you do about it? There are two options.The first option is where you are able to move the domain(s):
host each of the domain on their own web space with unique content.
The second option is where you are unable to host the domains on separate web space with separate unique content:
is to issue a HTTP status code: "301 Moved Permanently"
Below is the PHP code to redirect the traffic using an appropriate header and issue a HTTP 301 permanently moved status.
WAIT - is this correct? Yes, check with GoD (Google's official Documentation) here:
http://www.google.co.uk/support/webmasters/bin/answer.py?answer=34481http://www.google.co.uk/support/webmasters/bin/answer.py?answer=34464Using PHP you can use this to redirect traffic (for ASP, ColdFusion and .htaccess methods see
other relevant reading below) and tell googlebot the pages have moved, add this PHP to the top of your PHP pages:
$PHP_URI=$_SERVER['REQUEST_URI']; // folders and filename - used over PHP_SELF as will NOT pickup on filename from root access (webserver loads default file: index.php)
$HTTP_HOST=$_SERVER['HTTP_HOST']; // domain name, may include .www
if ($HTTP_HOST=="localhost") $main_url="localhost"; // useful for testing on localhost
else $main_url="www.dwalker.co.uk";// * CHANGE to your domain to be indexed
if( (!ereg("www.",$HTTP_HOST) AND ($HTTP_HOST!="localhost") ) OR (ereg("index.php",$PHP_URI)>0) )
{
$the_folder = str_replace("index.php", "", $PHP_URI);
header ('HTTP/1.1 301 Moved Permanently');
header ('Location: http://'.$main_url.$the_folder);
exit;
}
*Make sure you check which domain you should add here, and whether you it should or should not include "www". Only you can know this by checking your website stats and the current indexed domain and pages with Google (the above PHP code can be downloaded here:
http://www.dwalker.co.uk/blog/blog301redirect.zip )
Duplicate content is to be avoided at all costs, it will harm your website in the long term. You should always work towards UNIQUE content:
